Docker 在 python2.7-alpine 中的 docker 中安装 pandas 时构建失败
Docker build failing while installing pandas in docker in python2.7-alpine
我是 运行 Docker 中的一个烧瓶应用程序。我也在使用 Pandas。我正在使用 python2.7-alpine 图像。早些时候它工作正常，即我能够使用相同的配置构建图像。
但是现在我无法按照它所说的那样构建图像：
ERROR: Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-Sm9A7D/pandas/
The command '/bin/sh -c pip install -r /tmp/requirements.txt' returned a non-zero code: 1
我无法更改 python 版本。因为我的应用程序是建立在 python2 上的，并且很长一段时间都符合预期。

RUN pip install setuptools --upgrade
ADD requirements.txt /tmp/requirements.txt

来自 pandas 0.23.4 source：我们可以看到 numpy 的最低版本是 1.9.0:
min_numpy_ver = '1.9.0'
所以，如果你没有自己安装一个版本，pandas 只会安装一个最新的合适版本的 numpy，>1.9.0 适合你，这里是 numpy-1.17.0rc1，但是它需要 >python3.5 见 here，所以失败发生了。
python_requires='>=3.5'
最后，如果你查看numpy的源代码，你会发现1.16.4是最后一个支持python2.7的版本，见this，
python_requires='>=2.7,!=3.0.*,!=3.1.*,!=3.2.*,!=3.3.*',
所以，最终的解决方案：
Pre-install numpy 1.16.4，然后pandas 找到合适的numpy，不会给你安装最新的numpy。这样就不会报错了，具体步骤如下：
apk update
apk add build-base
pip install numpy==1.16.4
pip install pandas==0.23.4
对于Dockerfile，将上面的命令添加到一个运行可以修复：
RUN apk update && \
apk add build-base && \
pip install numpy==1.16.4 && \
pip install pandas==0.23.4
另外，你在问题中说：
Earlier it was working fine i.e. I was able to build images with the same configuration.
这是因为 numpy latest version 刚刚在 2019 年 7 月 1 日更新，在此之前，它始终是 1.16.4 版本，python27 没有问题，但现在，事情改变了...
